Avian Flu Restrictions Lifted: Minnesota Dairy Herds Reach Recovery Milestone

ST. PAUL, MINNESOTA – The Minnesota Department of Agriculture (MDA) announced this week that the state’s dairy herds are now officially clear of H5N1 avian influenza, marking an important milestone for the state’s livestock industry.

Status Cleared After Months of Monitoring

On September 10, the U.S. Department of Agriculture reclassified Minnesota’s status to “unaffected,” ending months of heightened surveillance. The shift comes after four months of testing raw milk samples with no new cases detected.

The update follows Minnesota’s only confirmed dairy herd infection reported in March 2025, when a herd tested positive for the avian influenza A virus. Since then, no further infections have been recorded.

Importance for the Dairy Industry

“We and the board are extremely grateful for the dairy industry’s cooperation in achieving this important milestone and for supporting the health and vitality of Minnesota’s livestock and poultry industries,” said MDA Commissioner Thom Petersen in a statement.

Avian influenza poses serious risks to livestock, particularly poultry, and has drawn national concern as cases spread to some U.S. dairy operations earlier this year. The recovery of Minnesota herds highlights the effectiveness of biosecurity measures and industry-wide vigilance.

National Recovery Trend

The MDA noted that most infected dairy farms nationwide have since recovered. While H5N1 is primarily a threat to poultry, it can also cause illness in humans who are exposed. State officials stressed that ongoing monitoring will remain in place to prevent future outbreaks.

Minnesota’s return to avian flu–free status signals relief for farmers and reinforces the state’s role as a major contributor to the Midwest’s agricultural economy. For more updates on regional agriculture and community health, follow ChicagoMusicGuide.com.
